Question

solve x²-5x-36=0 by factorization method ​

Answer 1

Answer:

x can be 9 or -4

Step-by-step explanation:

x² - 5x - 36 = 0

x² - 9x + 4x - 36 = 0......Splitting middle term

(x² - 9x) + (4x - 36) = 0

x (x - 9) + 4(x - 9) = 0

(x - 9) ( x + 4) = 0

Therefore, (x - 9) or (x + 4) = 0

x - 9 = 0                          x + 4 = 0

x = 0 + 9                         x = 0 - 4

x = 9                               x = -4

x can be 9 or -4
